What role does IPsec play on the VEN?

The role of IPsec on the Virtual Enforcement Node (VEN) is primarily related to its function in providing security for network communications. IPsec uses cryptographic techniques to ensure the confidentiality, integrity, and authenticity of data transmitted over IP networks. By implementing encryption and authentication protocols, IPsec protects data from unauthorized access and tampering, mitigating various security threats.

This is critical within the Illumio architecture, as it facilitates secure communications between the VEN and other components, ensuring that sensitive data remains protected during transmission. IPsec is not a firewall, nor does it manage user access control; rather, it enhances the security posture of the communication channels used by the network services that the VEN interacts with. The focus is specifically on the cryptographic methods that safeguard network traffic, rather than general access management or firewall functionalities.
